Additive manufacturing casting processes produce the molds in a fully automated layer-building process. In this process, an ultra-thin layer of sand is applied to a build platform and then selectively bonded by a print head. A new layer of sand is then applied and bonded again. These steps are repeated until the mold is completely printed.
